My 2001 Optima LX6 has 91,000 miles. To my knowledge the timing belt hasn't been replaced. Can anyone give me rough idea it may cost to have the timing belt checked for wear and replaced if needed? I'm in central Ohio.
I know this isn't cheap but it would be silly to trash a good engine for such an inexpensive part.

Did you get your quote from the dealer? I had mine done at Pep Boys for about $300.

2 recommendations:
- GET IT DONE SOON! The recommended interval is every 60K miles. One of my old Subaru's broke a belt at 63k, but subies have a "non-interference" engine. If the belt in a Kia breaks or slips you may be buying a replacement engine
- Have them check/replace the harmonic balancer at the same time. It is easy to replace while they are in there and if it is worn will affect how smoothly your engine runs (particularly at idle). I regret not having mine replaced as my car has a noticable vibration at idle and I don't want to pay another $300 just to fix a minor irritation (but I would have paid $60 for the part to have it done at the same time).

Tune up is due at 100K mi so might as well have it done now. I think they have to take the water pump of to get to the belt so I'd have them install a new water pump to. Not that familiar with KIA's but I know a Mitsubishi belt change is like $600. and with new water pump and belts runs about $800. and takes a good mechanic 8 hours.

"it would be silly to trash a good engine for such an inexpensive part." You got that rite and at 91K miles you are living on borrowed time. Busted pistons, bent connecting rod & valve stems and I hope you have deep pockets.
